I noted this post when you first posted it but skipped it as I didnt think it pertained to me. Perhaps I assumed,at any rate, there are 2 distinct things that I noted at the beginning of my illness/infection 13 yrs ago, one of which sounds like maybe what you are describing. I have constant white/yellow mucus drainage at the back of my throat, doesnt seemto correlate with any other symptoms. This also appeared with multiple raised visible erythematous lesions at the back of my throat. The other issue I noted was, what is known as multiple "fordyce spots". The med field says these are merely sebacious glands,however; Im suspicious given the chronicity of it: little coincidental.
